Flexible clamping device

- CITIC DICASTAL CO., LTD

The present disclosure provides a flexible clamping device, which is composed of a housing, a shaft I, a sleeve I, a cylinder, a connector, a shaft II, a clamping spring, a protective pad, a pressure block, a shaft III, a sleeve II and a bottom plate. The bottom plate is provided with two steps on which wheels having different sizes are fixed respectively. When the large-sized wheel is put on the bottom step, the cylinder drives the connector to move right in a plane, the protective pad on the pressure block presses the hub of the wheel, and the function of compacting the large-sized wheel is thus realized; when the small-sized wheel is put on the bottom step, the cylinder drives the connector to continuously move right in the plane, the protective pad on the pressure block presses the hub of the wheel, and the function of compacting the small-sized wheel is thus realized. The flexible clamping device in use can meet the requirement of mixed-line high precision clamping in the wheel burr brushing process, has the characteristics of ideal effect, high efficiency, safety and reliability in work and high degree of automation, and is particularly suitable for batch production on production lines.

RELATED APPLICATION

This application claims priority to Chinese Patent Application No. 201710103786.3, filed on Feb. 24, 2017, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to a flexible clamping device, and specifically to a clamp capable of clamping hubs having different sizes.

BACKGROUND

With the propos of flexible production, it has attracted more and more attention of enterprises. The automatic line production can greatly improve labor productivity, save labor, reduce cost, increase returns and the like for enterprises. In the automatic production process of hub industry, mixed-line production has become a present universal production mode, which highly requires the flexibility of machine tool equipment

SUMMARY

The present disclosure is aimed at providing a flexible clamping device, which can perform mixed-line machining via self structure and a compaction device according to hubs having different sizes to realize flexible production.

In order to fulfill the above aim, the present disclosure adopts the technical solution: a flexible clamping device is composed of a housing, a shaft I, a sleeve I, a cylinder, a connector, a shaft II, a clamping spring, a protective pad, a pressure block, a shaft III, a sleeve II and a bottom plate.

The housing is fixed below the bottom plate via four bolts, one end of the shaft I is fixed on the housing via a step, and the other end of the shaft I is fixed on the housing via the sleeve I and the cylinder. A cylinder rod at the upper end of the cylinder is in threaded connection with the connector, the connector is articulated with the pressure block via the shaft II and the clamping spring, and the pressure block is articulated to the housing via the shaft III and the sleeve II. One end of the shaft III is fixed outside the housing via a shaft shoulder, and the other end is fixed outside the housing via a pin.

The bottom plate is provided with two steps on which wheels having different sizes are fixed respectively. When the small-sized wheel is put on the bottom step, the cylinder rod of the cylinder moves up linearly, the cylinder simultaneously moves right in the circumferential direction by using the shaft I as a rotating shaft to drive the connector to move right in a plane, the pressure block moves right in the circumferential direction by using the shaft III as a rotating shaft, the protective pad presses the hub of the wheel, and the function of compacting the small-sized wheel is thus realized.

When the large-sized wheel is put on the top step of the bottom plate, the cylinder rod of the cylinder moves up linearly, the cylinder simultaneously moves right in the circumferential direction by using the shaft I as a rotating shaft to drive the connector to move right in a plane, the pressure block moves right in the circumferential direction by using the shaft III as a rotating shaft, the protective pad presses the hub of the wheel, and the function of compacting the large-sized wheel is thus realized.

The flexible clamping device of the present disclosure in use can meet the requirement of mixed-line high precision clamping in the wheel burr brushing process, has the characteristics of ideal effect, high efficiency, safety and reliability in work and high degree of automation, and is particularly suitable for batch production on production lines.
